Technique in total knee replacement is becoming increasingly recognized as the overriding primary factor in determining a good and long lasting result. It is more important than the type of interface (cemented, cementless, pressfic) or the type of prosthesis. However, with cementless total knee replacement, technique becomes even more important. The surgeon must achieve intimate contact between the cut surfaces of the bone and the prosthesis to assure both immediate pressfit and long-term biologic stability of the components. In addition, minor malalignment and instabilities may produce eccentric loading and micromotion of the cementless prosthesis sufficient to prevent biologic ingrowth. The surgeon considering cementless total knee replacement must hold to a high degree of technical accomplishment.
